Before the Monotones were given their respective names and such, I can't help but wonder if they were basically intended to be ambiguous/unisex characters... Big Jeffy aside, Rockin' Richard, Chrissy, and even Little Jerry were each played by Fran at least once in various different bits from the early 70s; it seems like isolated occurances with Richard and Jerry, but there's been other times when it seems suggested that Chrissy may have been female: in the album version of "Mad", Frank performed Chrissy using an angry-sounding Piggy-esque voice, likewise in "Good Morning Starshine", Caroll did Chrissy's speaking voice (using his mother voice from "Consider Yourself"), while Dr. Loretta Long provided singing voice. I can't even tell, with Jerry's exceptionally high voice, if Chrissy, or the Chrissy-esque character was intended to be female or not in "Surprise", but then again, the same puppet was used in a sketch with Grover about surprise where Caroll performed it (with Richard), though that was the same sketch where Fran played Little Jerry for some reason.
